Internet-of-things-based distributed power supply state monitoring device and method

Abstract

The present invention discloses an internet-of-things-based distributed power supply state monitoring device. The device of the invention comprises a front-end acquisition unit and a background monitoring terminal. The front-end acquisition unit is used for acquiring the working state of a distributed power supply and the meteorological environment information. The background terminal is used forrecording the acquired data of the front-end acquisition unit in real time, monitoring the state of the distributed power supply and evaluating the full life cycle of the distributed power supply in combination with the electrical monitoring data of the distributed power supply and the equipment ledger data of the distributed power supply. Through learning and training the training data set of thedistributed power supply, the health state of the distributed power supply is evaluated, and the fault of the distributed power supply is pre-judged. Based on the technology of the internet of things, the effective technical support means is provided for the friendly grid connection and the reliable operation of the distributed power supply.

Description

technical field [0001] The invention relates to the technical field of distributed power supply state monitoring, in particular to a distributed power supply state monitoring device and method based on the Internet of Things. Background technique [0002] Solar energy is the most accessible clean energy. In recent years, with the increasingly serious environmental problems and the policy support of the Chinese government, the proportion of distributed photovoltaic power generation in the power system is increasing. Photovoltaic power generation can use flat spaces such as Gobi, mountainous areas, and residential building roofs to lay photovoltaic solar panels for power generation, which is convenient and fast. Large-scale distributed power sources are also increasing. [0003] However, the problem of grid-connected distributed photovoltaics has become increasingly prominent. First of all, distributed photovoltaic equipment is affected by factors such as surface dust, ambi...

AI Technical Summary

Problems solved by technology

First of all, distributed photovoltaic equipment is affected by factors such as surface dust, ambient temperature, direct sunlight angle, and wind speed. It is greatly affected by the environment, and the failure rate of photovoltaic panels is high. The monitoring of photovoltaic equipment is not comprehensive

Secondly, photovoltaic panels and inverter equipment will naturally age, and there is no research on the status assessment and full life cycle management of photovoltaic power generation equipment

Most equipment such as photovoltaic panels and inverters only monitor electrical parameters, and other environmental state parameters can only be obtained by manual maintenance, which is labor-intensive and inefficient
